HYDRAULIC RAM.

Specification of Letters Patent No. 20,523, dated June 8, 1858.

vhydraulic ram, Fig. 2 is an end view of a ram, with the ordinary arrangement of open top valve chamber, representing the waste of water.

A A is the valve chamber; B the puppet valve; C C, the valve spindle; D a pipe to convey discharge water to cup E.

F is a weight connected with lever or beam G, by means of a key or set screw. Cup E is also arranged so as to be fastened on the lever or beam G, by means of a key or set screw.

H is a fulcrum to support lever or beam G.

I is a set screw. The dotted lines show the position of spindle when valve is closed.

K, Fig. 2, represents the ordinary open top arrangement of valve chamber; L L, irregular lines showing the waste water from the same.

The nature of my invention consists in arranging that part of the valve chamber above the valve, so as to prevent the water from wasting immediately after passing the Valve, by conducting it through a pipe or spout D, to a cup or basin E, by which means said cup is kept full for the purpose of overbalancing weight F, and thereby keeping the set screw I, clear of valve spindle C C, while the ram is in motion; the arrangement of cup E, with an opening in' bottom of sufiicient size to let the water esca e if the ram should stop, and thereby diminish the power of that end of the lever, to which said cup is attached, the weight F as shown, attached to lever G, of sufficient weight when operating in connection with fulcrum H, to bring down the point of set screw I, upon the top of spindle of valve C,

with suflicient force to overcome the weight of driving water, which holds up the valve and forces the valve to fall and the ram to start. The cup E and the weight H are so arranged that bot-h can be shifted upon the beam or lever, and fastened by key or screw so that the cup or 'basin when full, overbalances the weight F but when it is empty then said weight overbalances the cup.

The arrangement operates thus: While the ram is working instead of wasting the water immediately after passing the valve, as shown at L L, Fig. 2, it is conducted to cup E, by pipeor spout D, from which it is wasted, partly by overflowing, and partly through opening in the bottom of cup, the said cup being thus kept full while the ram is in motion. The set screw I is kept clear of touching or interfering with valve, or ram, so that not a particle of power is lost. As soon as t-he ram stops from any cause, then the cup ceases to get its supply, and immediately commences to empty, and consequently to get lighter; then the power is changed to weight F, which brings down the leverage upon the top of valve spindle, and forces it to drop, and at once the cup lls again, and then it being the heaviest, raises the lever clear of the valve, and then the ram works freely on as before. The arrows indicate the course of water.

What I claim as my invention, and desire to secure by Letters Patent is Using the water after passing the puppet valve by conducting it to a vessel or cup or basin, having a waste opening, or openings in the bottom, and used as a power upon a lever or beam to overbalance another power which is greater when the cup is empty, and least when the cup or basin is full, the conducting pipe D, the closed valve chamber A, the set screw I fixed over the valve, the fulcrum H, and beam or lever Gr, all the parts as substantially set forth, or used in combination for the purpose of keeping any hydraulic ram to which it may be attached in motion.
